Seepage of water: How to prevent water seepage in walls

Seepage in wall may be because of use of inferior raw materials during construction or not taking the water proofing measures seriously during the process of construction.  As the external walls of the concrete structure are exposed to the weather, prolonged contact with the rainwater can lead to cracks in the outer covering, giving way to water and moisture seepage in wall. This seepage in wall makes the walls damp. If seepage in wall is not treated in time, this dampness seeps into the interiors, ruining the wall paint.

Some of the other reasons that result in seepage in wall are:

Seepage in wall: What to do for interior walls?

Seepage in interior wall begins near the windows or door or the ceiling as these are the places where cracks are seen first. Repair the cracks and treat the dampened areas with water proof material and then paint it. Next, build cavity walls as they prevent the seepage in wall from exterior wall to interior wall.

One of the main reasons for seepage of water through to the interiors of your home, is the use of poor quality paint on the walls. These paints allow the moisture to seep through the concrete resulting in seepage in wall and thus damage the walls. Currently, the market is flooded with high-quality paints that are water-resistant and contain elements such as silicon that provide extra strength to areas which are most prone to water seepage. Opt for better quality paints after researching and consulting with your structural engineer, to avoid a lifelong hassle of seasonal renovation owing to seepage in wall.

How to prevent water seepage through walls if the construction is already done and there are cracks on the walls? You can use mortar to seal these cracks.

To prevent seepage on top floors or in independent houses, ensure that the terrace floor has a slope that does not allow water logging after rains or stagnant water due to leaking or overflowing water storage tanks. Check the terrace floor and parapet wall of the roof and fill up all the cracks present. Then, paint the parapet wall with waterproof paint.

A proper waterproofing solution safeguards the home from water leakages and dampness. There are various ways of waterproofing a roof surface. Opt for the best that suits the house construction.

Seepage in wall: How to treat bathroom leakage?

Seepage in wall in bathroom can be because of leakage in taps or sanitary fittings. So, mend any leak that exists. Also, gaps in the tiles and cracks on the floor or wall can cause leakage and these should be treated with mortar, cement or other water proof materials.

How to treat floor seepage?

Floor seepage occurs when there is moisture that rises on the ground and spoils the tiles. Use water proof materials for repairing the floor and while doing that make sure that there are no gaps between the tiles on the floor.

During construction, always opt for sturdy water pipes and ensure that the joints are well-sealed. Check for leakages in the water tanks and plumbing every six months and conduct an inspection of the drainage system.

Treatment of seepage before repainting

Repainting is often considered a solution to get rid of wall seepage. However, repainting does not treat the root cause of the seepage. When the seepage is severe, it causes water to drip from the walls and ceiling. It cannot be fixed with putty and paint only. While this temporarily helps to get rid of damp walls, the solution is not permanent. Nowadays, high-quality paints and painting procedures can help treat dampness on walls. For this, dirt and debris have to be removed, cracks filled and waterproof putties should be applied. New range of paints available today, are resistant to water and contain silicon that offers the walls extra protection against water seepage.
